Why is this happening?
I have more than enough capacity, the area is clearly covered by pipes, and yet these buildings are being abandoned due to lack of water.
This is only occurring after I resumed my saved game, but even with fast-forward time it doesn't resolve itself, it continues to worsen.
I have tried reloading multiple times, same result.
Edit: I thought I fixed it by adding additional power, didn't work, still getting this all over the map (second screen shot).

This was due to budget constraints. Make sure you have adequate day/night budget for water and power. They could make this more clear.
